Rose and Ron!
It came as nothing short of a relief when Ron suddenly heard Rose's strangled voice chanting out the exorcism from the opposite side of the room. Not only because she was ultimately saving both of them with all of the Latin chanting that he had been unable to memorize himself, but because it was a verification for him. Rose was alive. That bastard hadnn't offed her yet and he wasn't going to give him a chance at it now that he was here to protect her. Determined, Ron shoved the wrinkled mass of paper into his pocket and raised his wand once more. The demon looked downright mortified now that Rose was starting on with the exorcism instead of him. It was more consistent. Fluent. Quicker.
That might've pissed it off, though. The demon reared forward, arms reaching for Rose desperately. Ron didn't let it get close enough to try; he hexed it enough to send the monster reeling back a few steps. The motion was repeated a few times over. He wouldn't let the thing anywhere near his - he wouldn't let it near Rose.
It didn't seem like he had to put in a terribly large amount of hexing before the demon began to clutch at it's throat. Watching warily, Ron lowered his wand. It gagged, fell to it's knees, and continued to choke until a black smoked streamed out of it's mouth. The body that the demon had been possessing momentarily remained suspended; it was a loose, empty thing, completely void of life in every way possible now that it's puppet master had been sent away. Then the body collapsed, leaving both Ron and Rose alone for the first time since he had entered the room.
He certainly didn't waste any time. Pointing his wand at the bounds that kept Rose to the table she was on, Ron broke them apart and ran to the table without question.
He immediately winced when he saw how much blood there was. Red. Everywhere. "Bloody hell..." No, that didn't even begin to cover it. Anger snapped across his face like a whip and Ron turned to glare across the room, almost as though he were searching for Alastair himself. He was going to kill him. He was going to rip that sorry excuse of a demon apart until there was nothing left, he was going to -
His gaze turned back to Rose. No, he couldn't go after him. He had to take care of his daughter. She looked completely awful. Blood everywhere, gashes all over the sodding place. If he didn't get her out of here soon, chances were that him finding her wouldn't make a difference. He had to save her. Just like she had just saved him.
"Can you move?" Ron asked, already knowing the answer to his own question. He needed to hear her speak. He needed to make sure that she was still Rose, as little as the exorcism had been worth. "Are you -" He cut himself short, looking down at her with wide eyes. "I'm gonna get you outta here, all right?"
